Germanium bromides

Organogermanium fluorides can be prepared by reaction of germanium bromides with [Me4N]F (Equation (63))87 or XeF2 (Equation (64)).88 When a chloride precursor is used in the reaction with XeF2, a mixture of products results (Equation (65)).88...

Germanium triphenyl p-tolyl, (CgH5)3.Ge.(C6H,i.CH3), is formed when triphenyl germanium bromide is treated with, a large excess of p-tolyl magnesium bromide in ethereal solution. To complete the reaction, the ether is replaced by dry benzene and the whole boiled for eight hours. The reaction product is decomposed by dilute aqueous ammonium chloride and steam-distilled to remove ditolyl. The residue is then crystallised from petroleum ether and alcohol or from glacial acetic acid. The compound melts at 123° to 124° C. 

Germanium dimethylanilino triphenyl, (CPl3)2NCeH4.Ge(CeH5)3, from triphenyl germanium bromide, p-bromodimethylaniline, and sodium in xylene, forms brownish, crystalline nodules, M.pt, 140° to 141° C. The hydrochloride melts with decomposition at 105° to ll6° C., is insoluble in water and hydrochloric acid, but soluble in alcohol. When treated with alkali it gives the pure, free base.

The reactions of these complexes with hydrogen chloride proceed easily at room temperature and depending on stoichiometry can lead to partial or complete splitting of the polynuclear anions. The germanium bromide (QF5)3GeBr interacts with praseodymium mercurate to give the complex with [PrBr] cation ...
